3. Fitting a line y = mx + b using two points (x₁, y₁) and (x₂, y₂) can be modeled as b (30-0 m 1 A. Under what conditions does a solution always exist? Sketch a situation where a solution does not exist. B. Use Cramer's rule to compute b and m as functions of x₁, X2, Y₁, and y₂. Compare this solution with what you likely learned in high school.
